ARTHUR B. FARQUHAR, OF YORK, PENNSYLVANIA.

IMPROVEMENT IN MACHINERY FOR MAKING PLOW-HANDLES.

Specification forming part of Letters Patent No. 140,355, dated July 1, 1873; application filed March 7, 1873.

To all whom it may concern:

Be it known that I, ARTHUR B. FARQUHAR, of York, county of York, State of Pennsylvania, have invented certain Improvements in Machinery for making Plow-Handles, of which the following is a specification:

This invention consists of a form or holder within which the handle is clamped; of the arrangement by which the handle is centered in the form; and of the combination of these with the revolving-cutter heads for shaping the handle.

Figure 1 is a vertical section of the form and table upon which it rests. Fig. 2 is a plan of the same. Fig. 3 is a vertical crosssection of the entire machine. The three figures together embody'my machine.

In the following general description the letters refer to the annexed drawing.

A A is the form or holder, in which the handle B is held at one end by the dog 0, and by the clamps D and key E at the other. The form A A is made of two pieces of like dimensions, which, to combine greater stiffness with least weight, are of hard wood, fastened together at one end by a cross-piece, which also serves to hold the dog 0, and at the other by a cross-piece and the iron clamp D, as shown in Figs. 1 and 2. These sides A A have their edges shaped out as shown in Figs.1 and 3, so that when placed between the guides K K, Fig. 3, and drawn from the one end to the other upon the supports L L, the cutters J J will dress the handle to the required shape. To center and fasten the handle B in the form it is placed on the table I, which is provided with cleats or buttons M M, within which the form A A fits. H H are springguides attached to table I in such a position that they will guide the handle pressed between them truly to the center of the form A A. These spring-guides have their edges flared outward on the side toward D to facilitate the entrance of the handle between them. The block h, Figs. 1 and 3, is to bring the handle into its proper position in a vertical direction. F F, Fig. 2, are springguides similar to H H, their purpose being to center the handle at the other end of the form, but, as they embrace the handle at a point where it is not to be dressed by the cutter-heads, they are attached to the sides of the form A A. D is an iron band or clamp through which the handle passes, the opening in it being similar in shape to the cross-section of thehandle, but larger, to admit of the free action of the springs F F, and for driving the key E. I The handle B is thrust between thespring-guides F F through the clamp D, and between the spring-guides H H against the dog (J. These four springs, together with the block h and the lower side of clamp D, will guide the handles, whether of uniform size or not, truly into their required position in the form A A. To hold it while being dressed it is only necessary to drive it slightly on the dog (J, and drive in the key E, as represented in Figs. 1 and 2.

Having fastened the handle in the manner described, the operator lifts the form and handles from the table I and cleats M M, placing it between the guides K K, as shown in Fig. 3. The edges of the form A A resting on the supports L L it is drawn over the cutter-heads, which dress it to the shape required. The supports L are arcs of circles, which are concentric with and Whose planes are parallel with the cutter-heads J J.

I do not claim anything new in the cutterheads, as they have been in use before. What I claim to be new' and my invention is 1. Aform or holder having self-adjusting spring-guides F F and clamp D, when constructed and operated substantially as and for the purpose set forth.

2. The combination of the form or holder A A with the table I, having cleats M M and self-adjusting guide-springs H H, when constructed and operated substantially as and for the purpose set forth.

3. The combination of the form A A, the table I, and the cutter-heads J J, when all constructed and operated substantially as and for the purpose set forth.

ARTHUR B. FABQUHAR.
